How much of a difference in there between these two types of URLS? (in terms of SEO) http://www.keyword.com vs http://www.keyword.blogspot.com Is it worth the domain registration? Thanks.
The differences is: the first will be taken more seriously then the second. Since domain registration is usually very cheap - yes it's worth the money. If you are serious about making money online, go for the domain name even if it's not cheap. It just looks more professional.
